A month ago I decided to learn the song Misterioso on guitar, which seemed excruciatingly difficult but I figured if I could learn that one I could learn almost anything (and I’ve always loved those notes). I dutifully practiced it almost daily, and after 3 weeks it started sounding like the actual tune, and I started playing with alternate rhythms and figured out my own riff at the end and which blues chords sounded natural to transition into.
For my upcoming birthday, the fish paid for a couple of lessons from a real guitar teacher. My first lesson was a week ago yesterday, during which time I discovered when playing with my teacher that my guitar was at least a half-step out of tune. Upon returning home I tuned it to my trusty old pitch-pipe. An in-tune guitar is good, and I felt satisfied.
Since that first lesson I have been learning the notes — not that they’re called A, B, C etc., but which strings produce which pitches when plucked, etc.
Today the horrible realization struck me that the notes I’d learned to play Misterioso with are actually a half-step off! I quickly confirmed this by listening to the first few notes of Monk’s recording. Apparently I taught myself to play this piece in the key of f#. Which is very cool until you want someone to accompany you.
Of course this has occurred on the most fiendishly difficult fingering I’ve learned, and moving it down a half-step on the fretboard totally changes the fingerings. Should I relearn the piece in it’s true key, or stick with the key of f-sharp?
